Infinitely many sign-changing solutions for an asymptotically linear and nonlocal schrodinger equation

In this article, we consider the nonlocal schrodinger equation $$ -\mathcal{L}_K u+V(x)u=f(x,u),\quad x\in\mathbb{R}^N, $$ where \(-\mathcal{L}_K\) is an integro-differential operator and \(V\) is coercive at infinity, and \(f(x,u)\) is asymptotically linear for \(u\) at infinity. Combining minimax method and invariant set of descending flow, we prove that the problem possesses infinitely many sign-changing solutions.
